If you currently use a popular "free" email account at Yahoo!, Gmail, MSN, AOL, Hotmail, you are running naked through the public square. "If the service is free, the product is me."
Proton Mail is a hunk of Swiss cheese. Its byline is "Privacy by default." This sounds good, but a closer read of the agreement describes numerous relationships with third parties for which Proton says it cannot promise privacy, including Zendesk, Stripe, PayPal, Protom Group, and ProtonLabs (Proton Mail is "not responsible for the content of any website that we link to" including your content that passes through those third parties.).
Gmail is even more explicit about their abuse of your privacy. Their license is pure Orwellian double-speak. In a lead paragraph they acknowledge that your intellectual property is yours. They know that most unsuspecting people will stop reading right there and believe their use of Gmail is private. But then, in subsequent paragraphs, Gmail goes on to claim full rights to use your intellectual property worldwide in any way they like, royalty free, be it host, sell, reproduced, distribute, communicate, reformat, create derivative works, modify, publish, sublicense, share with contractors.
